The light meter has an illuminance range of 0.1 up to 2,000,000 lux, a measuring range of -5 to 22.9 EV (ISO100) and offers a special mode for photography and videography. In addition, the light meter is highly user-friendly thanks to its 2.7” LCD touchscreen. Finally, its dimensions are 94 x 176 x 49 mm and it weighs only 240 grams (excluding batteries).
